In this paper, we present a new methodology for integrating the sense of taste with the existing digital communication domain. First, we discuss existing problems and limitations for integrating the sense of taste as a digital communication media. Then, to assess this gap, we present a solution with three core modules: the transmitter, form of communication, and receiver. The transmitter is a mobile application, where the sender formulates a taste message to send. Then, for communication, we present a new extensible markup language (XML) format, the TasteXML (TXML) to specify the format of taste messages. As the receiver (actuator), we introduce Digital Taste Stimulator, a novel method for stimulating taste sensations on human. Initial user experiments and qualitative feedbacks were discussed mainly focusing on the Digital Taste Stimulator. We conclude with a brief overview of future aspects of this technology and possibilities on other application domains.

In this paper, we present a system, which could digitally stimulate the sense of taste (gustation) on human. The system utilizes electrical stimulation on human tongue to produce taste sensations. The initial experiments reveal that the method is viable and deserves further developments. This requires further analyses of the properties of electric pulses (current, frequency, and voltage) on tongue along with the stimulating material. The experimental results suggested that sourness, bitterness, and saltiness are the main sensations that could be evoked at present.

Thus far, most of the systems for generating taste sensations are based on blending several chemicals respectively, and there were no definite strategies to stimulate the sense of taste digitally. In this paper, a method for digitally actuating the sense of taste is introduced by actuating the tongue through electrical and thermal stimulations. The digital taste interface, a control system, is developed to stimulate the taste sensations digitally on the tongue. The effect of most persuading factors such as current, frequency, and temperature have been accounted for stimulating the tongue non-invasively. The experimental results suggested that sourness and saltiness are the main sensations that could be evoked while there are evidences of sweet and bitter sensations too.

We present a novel control system that enables digital stimulations of the sense of taste (gustation) on human to enhance remote multisensory interactions. The system uses two approaches to actuate taste sensations digitally: the electrical and thermal stimulations on tongue. The experimental results suggested that sourness and saltiness are the main sensations that could be evoked besides several evidences of sweet and bitter sensations.
